Data center electricity consumption
</h1>
<p>
Google uses a very small portion of global electricity. In an independent report, Stanford consulting professor Jonathan Koomey estimates that data centers use between 1.1% and 1.5% of global electricity (Growth in data center energy use 2005-2010). From our own accounting, we know that Google's data centers use about 1% of Koomey's worldwide data center estimate. This makes Google responsible for about 0.01% of global electricity use.
